Preventive Maintenance Schedules

Preventive Maintenance (PM) schedules are set by SEF to meet customers usage demands and manufacturer's maintenance specifications and warranty requirements. Each vehicle is assigned a PM schedule. SEF maintenance personnel work with vehicle users to keep all State vehicles in compliance with those schedules. Light-duty vehicles have a reminder sticker on their windshield; drivers should be aware of when the next PM service is due and schedule the vehicle to be serviced within that time.

Most PM Schedules have two types of services: an "A" service and a "C" service. The A service is routine maintenance and service, such as an oil change, tire rotation, lubrication, etc. that typically can be completed in less than one day. The C service is an in-depth service and maintenance process which can take much longer.

For actual services performed with each PM, contact your local SEF shop
